 Please always **squash** the pull request unless there are special circumstances. Do so, even if the PR contains only one commit. It creates a simpler history than a Merge Commit. "Special circumstances" are rare, and typically mean that there are a series of cleanly separated changes that will be too hard to understand if squashed together, or for some reason we want to preserve the ability to bisect them.
